| 1 | The state-of-the-art synthetic strategies for SAPO-34 zeolite catalysts in methanol-to-olefin conversion显示文摘Methanol-to-olefin(MTO)conversion has proven to be one of the most successful non-petrochemical routes for producing light olefins.Silicoaluminophosphate(SAPO)zeolite SAPO-34 is one of the best industrial catalysts for MTO conversion,but suffers from rapid deactivation due to the inherent diffusion bottleneck limited by the narrow eight-ring pore openings.To improve the MTO performance,considerable synthetic efforts have been devoted to decrease the crystal size of zeolites or introduce secondary larger pores in zeolite crystals to form hierarchical structures.This review mainly focuses on presenting the state-of-the-art synthetic strategies for nanosized and hierarchical SAPO-34 catalysts with excellent MTO performance.Furthermore,the industrialization of SAPO-34 catalysts for the MTO reaction,and some current problems and future prospects for the synthesis of SAPO-34 catalysts,are also pointed out.We expect that this review can not only shed some light on the preparation of SAPO-34 catalysts,but also stimulate the future development of high-performance SAPO-34 catalysts to meet the increasing demands of the chemical industry. | Qiming Sun Zaiku Xie Jihong Yu | 2018 | National Science Review2018，5，4： | 22 |
| 2 | Cerium-tannic acid passivation treatment on galvanized steel显示文摘A novel cerium-tannic acid passivation treatment was performed on galvanized steel. The corrosion resistance of cerium-tannic passivated samples was tested by dropping test with 0.5 wt.% CuSO4 aqueous solution. The mass loss per unit area of passivated samples was measured after the corrosion in 0.5 mol/L NaCl + 0.005 mol/L H2SO4 at room temperature for 96 h. The electrochemical behaviors of cerium, tannic acid, and cerium-tannic acid passivated samples on galvanized steel in 0.5 mol/L NaCl solution were investigated by polarization curves and electrochemical impendence spectra. The corrosion equivalent circuit was established according to the impedance characteristics. The results show that cerium-tannic acid treated samples exhibit better corrosion resistance than the sole cerium or tannic acid treated samples under the same condition. The mechanism of synergistic effect for cerium-tannic acid passivation on galvanized steel was discussed. | LIU Guangming YU Fei YANG Liu TIAN Jihong DU Nan | 2009 | Rare Metals2009，28，3： | 9 |
| 3 | Effect of Squeeze Casting on Microstructure and Mechanical Properties of Hypereutectic Al-xSi Alloys显示文摘The effect of squeeze casting on microstructure and mechanical properties of hypereutectic Al-xS i alloys(x = 15, 17.5, 22 wt%) was investigated in this study. Results show that microstructure of the hypereutectic Al-x Si alloys was obviously improved by squeeze casting. The amount of coarse primary Si phase decreased, while that of ?ne primary α-Al dendrites increased with the increase of squeeze casting pressure. Due to the decrease of coarse primary Si particles, cracking of the matrix was reduced, whilst the?ne microstructure, and mechanical properties of the squeeze casting alloys were improved. Compared with gravity casting alloys, mechanical properties of the hypereutectic Al-xS i alloys solidi?ed at 600 MPa were improved signi?cantly. Hardness of the squeeze casting hypereutectic Al-(15, 17.5, 22 wt%) Si alloys was improved by 15.91%, 12.23%, 17.48%, ultimate tensile strength was improved by 37.85%, 32.27%, 22.74%,and elongation was improved by 55.83%, 167.86%, 126.76%, respectively. Due to the uniform distribution of Si phases in squeeze casting Al-x Si alloys, their wear resistance was markedly enhanced. | Runxia Li Lanji Liu Lijun Zhang Jihong Sun Yuanji Shi Baoyi Yu | 2017 | Journal of Materials Science & Technology2017，33，4： | 8 |
| 4 | Luminescence anti-counterfeiting:From elementary to advanced显示文摘Luminescence anti-counterfeiting derives from the easily changeable luminescence behaviors of luminescence materials under the regulation of various external stimuli(such as excitation light,chemical reagent,heat,and mechanical force,etc.)and luminescence lifetime,which plays an important role in preventing forgery of currency,artworks,and product brands.According to the numbers of changes of anti-counterfeiting labels under various regulation conditions,luminescence anti-counterfeiting can be classified into three levels from elementary to advanced:single-level anti-counterfeiting,double-level anti-counterfeiting,and multilevel anti-counterfeiting.In this review,the recent achievements in luminescence anti-counterfeiting are summarized,and the regulation of various factors to anti-counterfeiting labels is discussed.Finally,existing problems,future challenges,and possible development directions are proposed in order to realize facile,quick,low-cost,environmentally friendly,and difficult-to-replicate advanced luminescence anti-counterfeiting. | Xiaowei Yu Hongyue Zhang Jihong Yu | 2021 | Aggregate2021，2，1： | 4 |
| 5 | Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety. | Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 4 |
| 6 | Differentiation of neuron-like cells from mouse parthenogenetic embryonic stem cells显示文摘Parthenogenetic embryonic stem cells have pluripotent differentiation potentials,akin to fertilized embryo-derived embryonic stem cells.The aim of this study was to compare the neuronal differentiation potential of parthenogenetic and fertilized embryo-derived embryonic stem cells.Before differentiation,karyotype analysis was performed,with normal karyotypes detected in both parthenogenetic and fertilized embryo-derived embryonic stem cells.Sex chromosomes were identified as XX.Immunocytochemistry and quantitative real-time PCR detected high expression of the pluripotent gene,Oct4,at both the mRNA and protein levels,indicating pluripotent differentiation potential of the two embryonic stem cell subtypes.Embryonic stem cells were induced with retinoic acid to form embryoid bodies,and then dispersed into single cells.Single cells were differentiated in N2 differentiation medium for 9 days.Immunocytochemistry showed parthenogenetic and fertilized embryo-derived embryonic stem cells both express the neuronal cell markers nestin,βIII-tubulin and myelin basic protein.Quantitative real-time PCR found expression of neurogenesis related genes(Sox-1,Nestin,GABA,Pax6,Zic5 and Pitx1) in both types of embryonic stem cells,and Oct4 expression was significantly decreased.Nestin and Pax6 expression in parthenogenetic embryonic stem cells was significantly higher than that in fertilized embryo-derived embryonic stem cells.Thus,our experimental findings indicate that parthenogenetic embryonic stem cells have stronger neuronal differentiation potential than fertilized embryo-derived embryonic stem cells. | Xingrong Yan Yanhong Yang Wei Liu Wenxin Geng Huichong Du Jihong Cui Xin Xie Jinlian Hua Shumin Yu Liwen Li Fulin Chen | 2013 | Neural Regeneration Research2013，8，4： | 4 |
| 7 | THEORY AND EXPERIMENTAL INVESTIGAION OF FLEXURAL WAVE PROPAGATION IN THIN RECTANGULAR PLATE WITH PERIODIC STRUCTURE显示文摘With the idea of the phononic crystals, a thin rectangular plate with two-dimensional peri-odic structure is designed. Flexural wave band structures of such a plate with infinite structure arecalculated with the plane-wave expansion (PWE) method, and directional band gaps are found in theΓX direction. The acceleration frequency response in the ΓX direction of such a plate with finitestructure is simulated with the finite element method and verified with a vibration experiment. Thefrequency ranges of sharp drops in the calculated and measured acceleration frequency responsecurves are in basic agreement with those in the band structures. Thin plate is a widely used componentin the engineering structures. The existence of band gaps in such periodic structures gives a new ideain vibration control of thin plates. | Wen Jihong Yu Dianlong Wang Gang Zhao Hongang Liu Yaozong | 2005 | Chinese Journal of Mechanical Engineering2005，18，3： | 4 |

| 9 | Help from space:grant-free massive access for satellite-based IoT in the 6G era显示文摘The Sixth-Generation(6G)standard for wireless communications is expected to realize ubiquitous coverage for massive Internet of Things(IoT)networks by 2030.Satellite-based communications are recognized as a highly promising technical enabler to satisfy IoT service requirements in the 6G era.This study analyzes multiple access technologies,which are essential for the effective deployment of satellite-based IoT.First,we thoroughly investigate the existing research related to massive access,including information-theory considerations as well as Non-Orthogonal Multiple Access(NOMA)and Random Access(RA)technologies.Then,we explore the influence of the satellite transmission environment on multiple access technologies.Based on this study,a Non-orthogonal Massive Grant-Free Access(NoMaGFA)scheme,which reaps the joint benefits of RA and NOMA,is proposed for asynchronous transmissions in satellite-based IoT to achieve improved system throughput and enhance the system robustness under varying traffics.Finally,we identify some important and interesting future developments for satellite-based IoT,including waveform design,transceiver design,resource allocation,and artificial intelligence-enhanced design. | Neng Ye Jihong Yu Aihua Wang Rongrong Zhang | 2022 | Digital Communications and Networks2022，8，2： | 3 |
| 10 | Surface‑Enhanced Raman Scattering Fiber Probe Based on Silver Nanocubes显示文摘Surface-enhanced Raman scattering(SERS)provides a novel method for low concentration molecular detection.The performances were highly dependent on the sizes,geometries and distributions of metal nanostructures.Here,highly sensitive SERS fber probe based on silver nanocubes(Ag NCs)was fabricated,by assembled nanostructures on planar and tapered fber tips.Ag NCs were synthesized by polyol method,and controlled by reductant content,reaction temperatures and crystal growth durations.Tapered fbers with diferent cone angles were prepared by chemical etching.The electromagnetic distribution simulation indicated that nanocubes had stronger electric feld between two cubes and vertex corners than nanosphere,under 532 nm laser excitation.The intensity could reach 53.52 V/m,for cubes with 70 nm edge length.The SERS performance of probes was characterized using crystal violet analyte.The detectable lowest concentration could reach 10^(-9) and 10^(-10) M for planar and tapered fber probes,respectively.The corresponding enhancement factor could be 9.02×10^(7) and 6.22×10^(8).The relationship between SERS peak intensities and analyte concentrations showed well linear,which indicated both fber probes could be applied for both qualitative and quantitative analysis.Furthermore,optimal cone angle of tapered fber SERS probe was 8.3°.The tapered fber SERS probes have highly sensitive activity and great potential in substance detection. | Miao Yu Qihang Tian Guangyuan He Kaimin Cui Jihong Zhang | 2021 | Advanced Fiber Materials2021，3，6： | 3 |
| 11 | Tailoring Porosity and Titanium Species of TS-1 Zeolites via Organic Base-assisted Sequential Post-treatment显示文摘The exploration of high-efficient catalysts based on hierarchical Ti-containing zeolites with optimized active titanium species distribution is of great value in enhancing the epoxidation of bulky olefins. Herein, hierarchical TS-1(MFI) zeolite with an extra-large external surface area(210 m2/g) and highly active octahedral- coordinated Ti species was prepared via organic base-assisted sequential post-treatment. Such a catalyst afforded a high turnover number value(TON, 114) in 1-octene epoxidation reaction, which was over twice than that(53) of the untreated conventional microporous TS-1 parent. According to the detailed characterization results, we revealed the hierarchical porosity construction effect of tetrapropylamonium hydroxide(TPAOH) treatment(first step) and the octahedral-coordinated Ti species fabrication effect of ethylamine(EA) treatment(second step) under hydrothermal condition. Such a facile post-treatment strategy reported in this work may provide guidance for the rational synthesis of TS-1 zeolite with enhanced catalytic activity. | XU Wenjing LI Li ZHANG Tianjun YU Jihong | 2022 | Chemical Research in Chinese Universities2022，38，1： | 2 |

| 14 | Research Advances of Epidemiological Characteristics and Diagnosis Technology of Rabies Virus显示文摘Rabies is a zoonosis caused by rabies virus,which has been characterized by infection of central nervous system. Rabies virus,which can cause fatal infections in humans and other mammals,has the characteristic of neurotropism,and the mortality caused by rabies is almost 100%. Routine diagnosis of rabies include clinical symptoms,while a final diagnosis depends on laboratory diagnostic methods,such as etiological diagnosis,serological diagnosis and molecular biological diagnosis. As a zoonotic infectious disease,rabies presents a global distribution situation,and the deaths caused by rabies virus infection in China ranks the second place in the world. Therefore,strengthening the recognition of disease etiology and epidemiology is very important to comprehensive prevention measures of rabies. The author mainly introduced the research progress on pathogen,epidemiology and diagnosis technology of rabies virus at home and abroad. In addition,the advantages and disadvantages of various methods were compared respectively,in order to provide a scientific basis for further study and rapid diagnosis of rabies. | Sun Yu Ma Shichun Wang Xiaoying Wei Wei Su Zenghua Ma Jihong Xie Qiao Xu Yi Dong Hao Shi Jianzhong | 2015 | Animal Husbandry and Feed Science2015，7，4： | 2 |
| 15 | Analysis of the relationship between bile duct and duodenal microbiota reveals that potential dysbacteriosis is the main cause of primary common bile duct stones显示文摘Bacteria play an important role in the formation of primary Common Bile Duct(CBD)stones.However,the composition and function of the microbiota of bile duct in patients with primary CBD stones remained to be explored.We utilized the 16S rRNA gene high-throughput sequencing technology to analyze the microbial diversity and community composition of biliary and duodenal microbiota in 15 patients with primary CBD stones and 4 patients without biliary tract diseases.Alpha diversity analysis showed that the microbiota richness was similar in bile and intestinal fluid;Beta diversity analysis showed that there were differences in the composition between biliary microbiota and the duodenal microbiota,but the abundance of the main groups showed similarities.The composition of the biliary microbiota from gallstone patients was more complex,as was the duodenal microbiota.Proteobacteria and Firmicutes were the dominant bacteria at phylum level,accounting for at least 75%of the total reads in each subgroup.Pseudomonas and EscherichiaShigella were the major genus among subgroups,but Escherichia-Shigella had increased abundance in duodenal microbiota with primary choledocholithiasis,which may play an important role in stone formation.It is noteworthy that Clostridiumsensu_stricto,Lachnospiraceae_UCG-008,Butyrivibrio and Roseburia which could produce short chain fatty acids(SCFAs),were significantly decreased in biliary microbiota with primary CBD stones(p<0.05).Our study provided new insights into the compositional of normal biliary microbiota.The micro-ecology of biliary and duodenal in patients with stones is complex and closely related,and there is a potential for dysbacteriosis.The decrease in abundance of certain major acid-producing bacteria affects the health of the biliary tract and thus leads to the formation of stones. | Zhitang Lyu Tingting Yu Lichao Zhang Xiaona Xu Yijun Zhang Jihong Li Zhirong Li Wei Zhang Senlin Hou | 2021 | Synthetic and Systems Biotechnology2021，6，4： | 2 |

| 17 | Study on the vibration band gap and vibration attenuation property of phononic crystals显示文摘Phononic crystals (PCs) are functional materials with periodic structures and elas- tic wave (vibration) band gaps, where propagation of vibrations with frequencies within band gaps is forbidden. PCs with finite periods can restrain the propagation of vibrations with frequencies in band gaps and thus has vibration attenuation property. Worldwide, many institutions and researchers are engaged in the re- search of PCs, however, studies on the vibration attenuation property of PCs are still limited. In this paper, we report our study of band gaps and vibration attenua- tion properties of 1) a simplified PC—periodic mass-spring structures, 2) longitu- dinal vibration of one-dimensional (1D-), 2D-, 3D-PCs, and 3) the flexural vibration of 1D- and 2D-PCs. These studies provide a foundation for the applications of PCs in vibration attenuation. | WEN JiHong WANG Gang YU DianLong ZHAO HongGang LIU YaoZong WEN XiSen | 2008 | Science China(Technological Sciences)2008，51，1： | 2 |
